All Dimensional Formula List PDF
An equation, which gives the relation between fundamental units and derived units in terms of dimensions is called dimensional formula (equation).
In mechanics, the length, mass, and time are taken as three base dimensions and are represented by letters L, M, T respectively.
Dimensions are the powers to which the fundamental quantities are raised to represent other physical quantities. Dimensional Formula is an expression in which dimensions of a physical quantity are represented in terms of fundamental quantities.
The expression showing the powers to which the fundamental units are to be raised to obtain one unit of a derived quantity is called the dimensional formula of that quantity.
If Q is the unit of a derived quantity represented by Q = MaLbTc, then MaLbTc is called dimensional formula, and the exponents a, b and, c are called the dimensions.
